[media] stk-webcam: Delete an unnecessary check before the function call "vfree"

2015-03-02T17:53:27Z

The vfree() function performs also input parameter validation. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software. Signed-off-by: Markus Elfring Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] media: drivers shouldn't touch debug field in video_device

2014-12-23T12:29:04Z

The debug field in struct video_device is for internal use only and drivers should mix that with their own debug module options. It is handled by the V4L2 core and users can set it using /sys/class/video4linux//debug. It has been deprecated for some time now, so it is time to remove it completely from the drivers.

[media] v4l: Support extending the v4l2_pix_format structure

2014-07-17T15:44:47Z

The v4l2_pix_format structure has no reserved field. It is embedded in the v4l2_framebuffer structure which has no reserved fields either, and in the v4l2_format structure which has reserved fields that were not previously required to be zeroed out by applications. To allow extending v4l2_pix_format, inline it in the v4l2_framebuffer structure, and use the priv field as a magic value to indicate that the application has set all v4l2_pix_format extended fields and zeroed all reserved fields following the v4l2_pix_format field in the v4l2_format structure. The availability of this API extension is reported to userspace through the new V4L2_CAP_EXT_PIX_FORMAT capability flag. Just checking that the priv field is still set to the magic value at [GS]_FMT return wouldn't be enough, as older kernels don't zero the priv field on return. To simplify the internal API towards drivers zero the extended fields and set the priv field to the magic value for applications not aware of the extensions.

[media] media: remove the setting of the flag V4L2_FL_USE_FH_PRIO

2014-07-04T19:14:59Z

Since all the drivers that use `struct v4l2_fh' use the core priority checking, the setting of the flag in the drivers can be removed. Signed-off-by: Ramakrishnan Muthukrishnan Reviewed-by: Hans Verkuil Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] stk-webcam: implement support for count == 0 when calling REQBUFS

[media] stk-webcam: zero the priv field of v4l2_pix_format

The priv field should be set to 0. In this case the driver abused the priv field for internal housekeeping. Modify the code so priv is no longer used for that purpose. Signed-off-by: Hans Verkuil Tested-by: Arvydas Sidorenko Signed-off-by: Mauro Carvalho Chehab
